ITEM 1A. RISK FACTORS

Current report

Further, in January 2025, President Trump signed executive orders that, among other things, directed federal executive departments and agencies to initiate a regulatory freeze for certain rules that have not taken effect, pending review by the newly appointed agency head, and called upon the EPA to submit a report on the continuing applicability of its endangerment finding for greenhouse gas emissions under the Clean Air Act and issue guidance on the “social cost of carbon” to consider whether such metric should be eliminated. Moreover, in January 2025, President Trump signed an executive order calling to terminate all environmental justice offices and positions in the federal government, as well as any environmental justice initiatives, programs or other activities. It is unclear the impact the Trump administration or these new executive orders will have on the laws, rules and regulations applicable to us or on our business, financial condition and results of operations, and we cannot predict future developments related hereto.

Current report

We are subject to sustainability efforts risks that could adversely affect our reputation and our business and results of operations.

Current report

Views about sustainability- and environmental-related issues are diverse, dynamic, and rapidly changing. For instance, there exists anti-environmental, social and governance (“ESG”) sentiment among certain stakeholders and government institutions, which has gained momentum across the U.S. While many companies and investors continue to focus on ESG matters, there has been an increase in anti-ESG initiatives and sentiment which may serve as a concern in the future, particularly in light of recent executive orders by President Trump. The future impact of any actions by the current administration on existing ESG policies and regulations cannot be predicted at this time, particularly given that such new orders are likely to face legal challenges. However, in the interim, such anti-ESG-related policies, legislation, initiatives, litigation, legal opinions, and scrutiny could result in less demand for our products and offerings, which can affect our business and results of operations. Further, we could be exposed to reputational, financial, and legal risk as a result of anti-ESG policies and regulations that may be enacted under the current administration, and our ability to retain and attract customers and employees may be negatively impacted as a result thereof.

Current report

Our revenue has been highly concentrated among a small number of customers, and our results of operations could be harmed if we lose a key revenue source and fail to replace it.

Current report

Our annual revenue has been highly concentrated, with a few customers accounting for a significant percentage of our total revenue. For the years ended December 31, 2024 and 2023, our two largest customers represented approximately 86% and 87% of total revenue, respectively. We expect that a relatively small number of customers will continue to account for a substantial portion of our revenue for the foreseeable future.

Current report

As a result of this revenue concentration, our results of operations could be adversely affected by the decision of a single key customer to cease using our technology or products or by a decline in the number of customers that are seeking to adopt our technology.

Current report

Our revenue concentration may also pose credit risks which could negatively affect our cash flow and financial condition.

Current report

We might also face credit risks associated with the concentration of our revenue among a small number of customers. Our failure to collect receivables from any customer that represents a large percentage of receivables on a timely basis, or at all, could adversely affect our cash flow or results of operations.

Current report

Although we currently maintain product liability coverage, which we believe to be adequate for the continued operation of our business, such insurance may become difficult or impossible to obtain in the future on terms acceptable to us. Moreover, our insurance coverage includes customary exclusions and conditions, may not cover certain specialized applications and generally does not cover warranty. A successful product liability claim or series of claims against us, including one or more consumer claims purporting to constitute class actions or claims resulting from extraordinary loss events, in excess of or outside our insurance

Current report

coverage, or a significant warranty claim or series of claims against us, could materially decrease our liquidity, impair our financial condition and adversely affect our results of operations. Furthermore, regardless of the outcome, product liability claims can be expensive to defend, divert the attention of management and other personnel for significant periods of time and cause reputational damage.

Current report

Further, the materials that our subcontractors may import from time to time are generally at prices that support our current operating margins. These imports may be subject to custom requirements, tariffs, and quotas set by governments through mutual agreements or unilateral actions. The U.S. tariffs on steel and other imported goods may increase the costs of our foreign sourced materials, and any escalation in the tariffs may increase the impact, including without limitation recent tariffs against goods imported from China, Mexico, and Canada recently enacted by the current administration, as modified from time to time, and any retaliatory tariffs issued in response thereto. In case our operating costs increase materially as a result of any implemented tariffs, in order to sustain current operating margins, we may increase the costs of our products to customers and end users, or find alternative, similarly priced sources that are not subject to tariffs, which may delay our operations. If we are unable to effectively implement countermeasures to any proposed, or implemented, tariffs, our operating margins will be impacted.

Current report

Our subcontractors ability to import products in a timely and cost-effective manner may also be affected by conditions at ports or issues that otherwise affect transportation and warehousing providers, such as port and shipping capacity, high demand for ocean freight, labor disputes, hostilities or terrorism against ocean vessels or changes in shipping routes to avoid the same, severe weather, or increased homeland security requirements in the U.S. and other countries. These issues could delay importation of materials, increase our transit costs, or require us to locate alternative ports or warehousing providers to avoid disruption to customers. These alternatives may not be available on short notice or could result in higher transit costs, which could have an adverse impact on our business and financial condition.

Current report

There may be future sales of our common stock, or a perception that these sales could occur, which events could cause the price of our common stock to decline.

Current report

Sales of a substantial number of shares of our common stock in the public market or the perception that such sales might occur could materially adversely affect the market price of the shares of our common stock. For instance, the securities issued in our recent equity offerings (see “Note 8 – Equity” for additional information), as well as the Warrant Shares, have been registered for resale and are freely tradable without restriction or further registration under the Securities Act. As a result, a substantial number of shares of common stock may be sold in the public market, subject to certain beneficial ownership restrictions. We cannot predict the effect, if any, that market sales of those shares of common stock or the availability of those shares for sale will have on the market price of our common stock.

Current report

We will have broad discretion as to the proceeds that we receive from the cash exercise by any holder of our Warrants, and we may not use the proceeds effectively.

Current report

We may receive up to approximately $22.5 million in aggregate gross proceeds from cash exercises of our outstanding Warrants based on the per share exercise price of such Warrants, and to the extent that we receive such proceeds, we intend to use the net proceeds from cash exercises of the Warrants for working capital, research and development, marketing and sales, and general corporate purposes. We have considerable discretion in the application of such proceeds. You must rely on our judgment regarding the application of the net proceeds from cash exercises of the Warrants, which may be used for corporate purposes that do not improve our profitability or increase the price of our shares of common stock. Such proceeds may also be placed in investments that do not produce income or that lose value. The failure to use such funds by us effectively could have a material adverse effect on our business, financial condition, operating results and cash flow.

Current report

You may experience future dilution as a result of issuance of the Warrant Shares, future equity offerings by us and other issuances of our common stock or other securities. In addition, the issuance of the Warrant Shares, to the extent the Warrants are exercisable, and future equity offerings and other issuances of our common stock or other securities may adversely affect our common stock price.

Current report

You may experience future dilution as a result of the issuance of the Warrant Shares and other issuances of our common stock or other securities. In order to raise additional capital, if needed, we may in the future offer additional shares of our common stock or other securities convertible into or exchangeable for our common stock at prices that may not be the same as the price per share as prior issuances of common stock. We may not be able to sell shares or other securities in any other offering at a price per share that is equal to or greater than the price per share previously paid by investors, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional shares of our common stock or securities convertible into common stock in future transactions may be higher or lower than the prices per share for previous issuances of common stock or securities convertible into common stock paid by certain investors. In addition, the exercise price of the Warrants may be equal to or greater than the price per share previously paid by certain investors. You will incur dilution upon exercise of any outstanding stock options, warrants or upon the issuance of shares of common stock under our equity incentive programs.

Reworded paragraphs (26)

Previous wording

We are a company with a limited operating history and limited revenues to date. We have incurred losses since our inception and expect to experience operating losses and negative cash flows for the foreseeable future. As of December 31, 2023, we had a total accumulated deficit of approximately $93.7 million. We anticipate our losses will continue to increase from current levels because we expect to incur additional costs and expenses related to commercialization activities, product development, consulting costs, marketing and other promotional activities. In addition, we expect to continue incurring costs related to human capital development and strategic partnership development. We may never generate significant revenue and we may never be profitable.

Previous wording

Our business is capital-intensive and requires capital investments in order for it to develop. Our cash on hand will likely not be sufficient to meet all of our future needs because our target customers are, in general, slow to adopt new technologies, and we anticipate that we will require substantial additional funds in excess of our current financial resources for research, development and commercialization of our technology, to obtain and maintain patents and other intellectual property rights in our technology, and for working capital and other purposes, the timing and amount of which are difficult to ascertain. Until our technology generates revenues sufficient to support our operations, we plan to obtain the necessary working capital for operations through the sale of our securities, but we may not be able to obtain financing in amounts sufficient to fund our business plans. If we cannot obtain additional funding when and as needed, our business might fail.

Our business is capital-intensive and requires capital investments in order for it to develop. Our cash on hand will likely not be sufficient to meet all of our long-term future needs because our target customers are, in general, slow to adopt new technologies, and we anticipate that we will require substantial additional funds in excess of our current financial resources for research, development and commercialization of our technology, to obtain and maintain patents and other intellectual property rights in our technology, and for working capital and other purposes, the timing and amount of which are difficult to ascertain.

Previous wording

If we are unable to effectively demonstrate our technology in a timely fashion, gain recognition in our market segments, and develop a critical level of successful sales and product installations, we may not be able to successfully achieve sales revenue and our results of operations and financial condition would then suffer. Our ability to achieve future revenue will depend significantly upon achieving a critical mass of market awareness and sales to potential customers of our products. While we plan to achieve this awareness over time, there can be no assurance that awareness of our Company and technology will develop in a manner or pace that is necessary for us to achieve acceptance and profitability in the near term.

Previous wording

Further, we cannot predict the rate of adoption or acceptance of our technology by potential customers. While we have demonstrated our technology, this does not guarantee the industrial combustion market will accept it, nor can we control the rate at which such acceptance may be achieved. In certain market segments of ours, there is a well-established channel with a limited number of companies engaged in reselling to our target customers. Failure to achieve productive relations with a sufficient number of these prospective partners may impede adoption of our technology. Additionally, some potential customers in our target industries are historically risk-averse and have been slow to adopt new technologies. If our technology is not widely adopted in the industrial combustion market, we may not earn enough by selling or licensing our technology to support our operations, recover our research and development costs or become profitable and our business could fail.

Previous wording

environmental regulations in the U.S. and in other industrialized countries are modified in the future, or even relaxed, our technology may not produce the results required, or may even be unnecessary, to comply with the modified regulations. If federal, state or local regulatory agencies relax the clean air regulations our technologies are designed to address, or our customers cannot obtain air emission permits with our products, our business and results of operations could be materially adversely affected.

Current wording

The negative environmental impacts of industrial activity have given rise to significant environmental regulation in industrialized countries. These regulations are important incentives in the adoption of technologies like ours. To the extent that environmental regulations in the U.S. and in other industrialized countries are modified in the future, or even relaxed, our technology may not produce the results required, or may even be unnecessary, to comply with the modified regulations. If federal, state or local regulatory agencies relax the clean air regulations our technologies are designed to address, or do not effectively enforce them, or our customers cannot obtain air emission permits with our products, or permits to proceed with projects in general, our business and results of operations could be materially adversely affected.

combustion market segment. Success of any collaborative arrangements we enter into will depend, in part, on whether those with whom we collaborate fulfill their contractual obligations satisfactorily. If a party with whom we collaborate fails to perform its contractual obligations satisfactorily, we may be unable to make the additional investments or provide the added services that would be required to compensate for that failure. If we are unable to adequately address any such performance issues, our reputation may be materially adversely affected and we may be exposed to legal liability. Our inability to successfully maintain collaborative relationships, once we enter into them, or to enter into new collaborative arrangements, could have a material adverse effect on our results of operations.

Current wording

Collaborative arrangements involve risks that participating parties may disagree on business decisions and strategies. These disagreements could result in delays, additional costs, risks of litigation, and failure of the development of our technology within the combustion market segment. Success of any collaborative arrangements we enter into will depend, in part, on whether those with whom we collaborate fulfill their contractual obligations satisfactorily. If a party with whom we collaborate fails to perform its contractual obligations satisfactorily, we may be unable to make the additional investments or provide the added services that would be required to compensate for that failure.

Previous wording

The combustion industry is characterized by intense competition. Many of our potential competitors have better name recognition and substantially greater financial, technical, manufacturing, marketing, personnel and/or research capabilities than we do. Although at this time we do not believe that any of our potential competitors have technology similar to ours, we are aware certain potential competitors are attempting to develop similar products. Many firms in the combustion industry have made and continue to make substantial investments in improving their technologies and manufacturing processes. In addition, they may be able to price their products below the marginal cost of production in an attempt to establish, retain or increase market share. Because of these circumstances, it may be difficult for us to compete successfully in the combustion market.

Previous wording

We are exposed to risks of doing business in China. As a result, the economic, political, legal and social conditions in China could have a material adverse effect on our business. In addition, the legal system in China has inherent uncertainties that may limit the legal protections available in the event of any claims or disputes that we may have with third parties, including our ability to protect the intellectual property we use in China. As China’s legal system is still evolving, the interpretation of many laws, regulations and rules is not always uniform and enforcement of these laws, regulations and rules involve uncertainties, which may limit the remedies available in the event of any claims or disputes with third parties. Some of the other risks related to doing business in China include:

We cannot provide assurance that global supply-chain constraints will not adversely affect our commercialization efforts.

Current wording

We cannot provide assurance that global supply-chain constraints and the threat of, or implementation of tariffs on imported or exported goods and materials will not adversely affect our commercialization efforts and business operations.

Previous wording

The impact of the global supply-chain constraints has been moderate for our company, reflecting generally modest increases in lead-time commitments from our suppliers and strategic partners. While these constraints have not had a material impact to-date, we can provide no assurance that our business will not be affected by in the future.

Current wording

The impact of the global supply-chain constraints has been moderate for our company, reflecting generally modest increases in lead-time commitments from our suppliers and strategic partners. While these constraints have not had a material impact to-date, we can provide no assurance that our business will not be affected by in the future. Our products utilize components manufactured from materials that are frequently imported, and any increase in the cost of materials may increase costs and may impact our profit margin on goods sold. Tariffs applied to exported goods may inhibit our ability to develop our business overseas. In addition, the countries from which our products and materials are manufactured or imported may, from time to time, impose additional quotas, duties, tariffs, or other restrictions on their imports or adversely modify existing restrictions. Adverse changes in these import costs and restrictions, or our strategic partners’ and suppliers’ failure to comply with customs regulations or similar laws, could harm our business. However, it is not always possible to replace a supplier on short notice without disruption in our operations, and replacement of a supplier is often at higher prices.

Previous wording

We currently have a collaboration agreement in place with Zeeco, Inc. (“Zeeco”). If Zeeco, or any of our subcontractors, is unable to provide services that meet or exceed our customers’ expectations or satisfy our contractual commitments, our reputation, business and operating results could be harmed. In addition, if we are unable to avail ourselves of warranties and other contractual protections with providers of products and services, we may incur liability to our customers or additional costs related to the affected products and services, which could adversely affect our business, financial condition and results of operations. Moreover, any delays, malfunctions, inefficiencies or interruptions in these products or services could adversely affect the quality and performance of our projects and require considerable expense to find replacement products and to maintain and repair our projects. This could cause us to experience interruption in our production and distribution of our products, difficulty retaining current relationships and attracting new relationships, or harm our brand, reputation or growth. Additionally, because the Company’s contracts generally include progress payments from customers upon the completion of certain defined milestones, the revenue recognition of such project will depend on our subcontractor’s services in order for us to be able to achieve such milestones timely. Any subcontractor delays in fulfilling our contracts may result in delay of revenue recognition by the Company, which in turn can affect our financial condition and results of operations.

Current wording

These investments, as well as any cash deposit in bank accounts, are subject to general credit, liquidity, market, inflation and interest rate risks, which may be exacerbated by unusual events, such as higher interest rates, potential recession and debates on the debt-ceiling, which may affect various sectors of the financial markets and lead to global economic slowdown and high inflation. If the global credit and capital market continues to experience volatility or deteriorates, and to the extent we make future investments, our investment portfolio may be impacted, and we could determine that some or all of our investments experienced an other-than-temporary decline in fair value, requiring impairment, which could adversely impact our financial position and operating results.

Previous wording

We completed the initial public offering of our common stock in April 2012. Since that time, our common stock (NASDAQ: CLIR) has traded as low as $0.35 per share and as high as $11.75 per share based upon daily closing prices, and day-to-day trading has been volatile at times. This volatility may continue or increase in the future. The market price for the securities may be significantly affected by factors such as progress in the development of our technology, agreements with research facilities or co-development partners, commercialization of our technology, variations in quarterly and yearly operating results, general trends in the alternative energy industry, and changes in state or federal regulations affecting us and our industry. Furthermore, in recent years the stock market has experienced extreme price and volume fluctuations that are unrelated or disproportionate to the operating performance of the affected companies, such as the market reactions to internet marketed ‘short squeezes’. Such broad market fluctuations may adversely affect the market price of our securities.

We will require additional financing to fund research, development and commercialization of our technology, to obtain and maintain patents and other intellectual property rights in our technology, and for working capital and other purposes. We may not be able to obtain financing on favorable terms, if at all. If we raise additional funds by issuing equity securities, the percentage ownership of our then-current shareholders will be reduced. Further, we may have to offer new investors in our equity securities rights that are superior to the holders of common stock, which could adversely affect the market price and the voting power of shares of our common stock. If we raise additional funds by issuing debt securities, the holders of these debt securities would similarly have some rights senior to those of the holders of shares of common stock, and the terms of these debt securities could impose restrictions on operations and create a significant interest expense for us which could have a materially adverse effect on our business and results of operations.

As of December 31, 2023, we had outstanding options for the purchase of 2,759 thousand shares of common stock and 671 thousand shares of outstanding restricted stock units (“RSUs”). Under the ClearSign Technologies Corporation 2021 Equity Incentive Plan and the ClearSign Technologies Corporation 2013 Consultant Stock Plan (collectively, the “Plans”), we have the ability to grant awards of shares, RSU’s or options to purchase shares of our common stock to employees, officers, directors, independent contractors and agents. Furthermore, the Plan provides for increases in the number of shares available for awards based on the terms outlined in such Plan. Certain holders may sell these shares in the public markets from time to time, without limitations on the timing, amount or method of sale. If our stock price rises, the holders may exercise their options and RSUs and sell a large number of shares. This could cause the market price of our common stock to decline.

As of December 31, 2024, we had outstanding options for the purchase of 2,943 thousand shares of common stock and 864 thousand shares of outstanding restricted stock units (“RSUs”). Under the ClearSign Technologies Corporation 2021 Equity Incentive Plan (the “2021 Plan”) and the ClearSign Technologies Corporation 2013 Consultant Stock Plan (the “2013 Consultant Plan,” and collectively, the “Plans”), we have the ability to grant awards of shares, RSU’s or options to purchase shares of our common stock to employees, officers, directors, independent contractors and agents. Furthermore, the Plan provides for increases in the number of shares available for awards based on the terms outlined in such Plan. Certain holders may sell these shares in the public markets from time to time, without limitations on the timing, amount or method of sale. If our stock price rises, the holders may exercise their options and RSUs and sell a large number of shares. This could cause the market price of our common stock to decline.

Previous wording

We are authorized to issue 2.0 million shares of “blank check” preferred stock, with such rights, preferences and privileges as may be determined from time-to-time by our board of directors. Our board of directors is empowered, without shareholder approval, to issue preferred stock in one or more series, and to fix for any series the dividend rights, dissolution or liquidation preferences, redemption prices, conversion rights, voting rights, and other rights, preferences and privileges for the preferred stock. No shares of preferred stock are presently issued and outstanding and we have no immediate plans to issue shares of preferred stock. The issuance of shares of preferred stock, depending on the rights, preferences and privileges attributable to the preferred stock, could adversely reduce the voting rights and powers of the common stock and the portion of our assets allocated for distribution to common stockholders in a liquidation event, and could also result in dilution in the book value per share of our common stock. The preferred stock could also be utilized, under certain circumstances, as a method for raising additional capital or discouraging, delaying or preventing a change in control of the Company, to the detriment of our shareholders. We cannot assure you that we will not, under certain circumstances, issue shares of our preferred stock.

Current wording

Our certificate of incorporation (as amended, the “certificate of incorporation”) provides that the Court of Chancery of the State of Delaware is the exclusive forum for certain disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.

Previous wording

Current wording

This provision does not apply to suits brought to enforce a duty or liability created by the Securities Act, the Exchange Act or any other claim for which the U.S. federal courts have exclusive jurisdiction. In addition, unless we consent in writing to the selection of an alternative forum, to the fullest extent permitted by law, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause or causes of action arising under the Securities Act, including all causes of action asserted against any defendant to such complaint.

Previous wording

However, these choice of forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, or other employees. Further, these choice of forum provisions may increase the costs for a stockholder to bring such a claim and may discourage them from doing so.

Current wording

For the avoidance of doubt, this provision is intended to benefit and may be enforced by us, our officers and directors, the underwriters to any offering giving rise to such complaint, and any other professional entity whose profession gives authority to a statement made by that person or entity and who has prepared or certified any part of the documents underlying the offering.

Current wording

While the Delaware courts have determined that such choice of forum provisions are facially valid, a stockholder may nevertheless seek to bring a claim in a venue other than those designated in the exclusive forum provisions, and there can be no assurance that such provisions will be enforced by a court in those other jurisdictions. If a court were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions. For example, the Court of Chancery of the State of Delaware recently determined that the exclusive forum provisions of federal district courts of the United States of America for resolving any complaint asserting a cause of action arising under the Securities Act is not enforceable. We note that investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder.

Current wording

Our bylaws obligates us to indemnify each of our directors or officers who is or is threatened to be made a party to or witness in a proceeding by reason of his or her service in those or certain other capacities, to the maximum extent permitted by Delaware law, from and against any claim or liability to which such person may become subject or which such person may incur by reason of his or her status as a present or former director or officer of us or serving in such other capacities. In addition, we may be obligated to reimburse the expenses reasonably incurred by our present and former directors and officers in connection with such proceedings. As a result, we and our stockholders may have more limited rights to recover money damages from our directors and officers than might otherwise exist absent these provisions in our bylaws or that might exist with other companies, which could limit your recourse in the event of actions that are not in our best interests.

Previous wording

As a public company reporting to the Securities and Exchange Commission, we incur significant legal, accounting, investor relations, printing, board compensation, and other expenses that we did not incur as a private company. These costs totaled $1.3 million in 2023. We are subject to the reporting requirements of the Securities Exchange Act of 1934 and the Sarbanes-Oxley Act of 2002 (with the exception of the requirement of auditor attestation of internal control over financial reporting from which we are currently excluded as a non-accelerated filer company), as well as rules subsequently implemented by the Commission that impose significant requirements on public companies, including requiring establishment and maintenance of effective disclosure and financial controls and changes in corporate governance practices. In addition, there are significant corporate governance and executive compensation-related provisions in the Dodd-Frank Wall Street Reform and Protection Act that as we grow could increase our legal and financial compliance costs, make some activities more difficult, time-consuming or costly and may also place undue strain on our personnel, systems and resources. Our management and other personnel continually devote a substantial amount of time to these compliance initiatives. Furthermore, these rules and regulations may make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be more difficult for us to attract and retain qualified people to serve on our board of directors, our board committees or as executive officers.
